This was a movie I watched on VHS back  in a period from 94-99 I think…if I remember correctly the movie was about a couple being taken hostage by a guy but in a twist it appears the girl was working with the kidnapper all along, I think there was a scene of the kidnapper throwing the girl over his shoulder and slapping her rear and her pretending to be disgusted by it in front of her boyfriend/guy who got kidnapped.

It might have had a grenade or a bomb on the cover I’m not even sure anymore.
